Claims. (01. 101-295) My invention relates more particularly to thosepresses described, in United States Patent No. 1,961,828, issued toGeorge A. Rutkoskie, which are designed to print spots of wax carbon onsheets of paper in predetermined locations. In

the patent referred to, the fact is disclosed that wax carbon must bemelted to use it and it must be maintained at a critical temperature inorder to produce a satisfactory job. Moreover, due to the fact that thewax carbon compound, when melted, is not tacky; it is essential that therollers be positively driven as the frictional contact of the rollerswill not cause them to rotate due to the said lack of tack.

, My invention has for its object to adapt a standard Sheridanvertically reciprocating embossing press to print spots of wax carbon onsheets of paper.

My means of accomplishing the foregoing objects may be more readilyunderstood by having reference to the accompanying drawings which arehereunto annexed and are a part of this specification, in which I showonly my attachment and such fragmentary parts of the press as arenecessary.

Fig. 1 is a side elevation of a press equipped with my improvement;

Fig; 2 is a diagrammatic view showing the rollers;

Fig. 3 is a top or plan view;

Fig. 4 is the opposite side elevation showing I the means employed topositively drive the rollers; and

Fig. 5 is a bottom plan view showing the means employed to drive theform rollers.

Similar reference numerals refer to similar parts throughout the entiredescription.

As shown in the drawings, the press has standards I and 2 which areprovided with vertical guides 3 and 4 in which is mounted an adjustableplaten 5 adapted to contact the vertically reciprocating type bed 6,this being standard construction for a press of this character. Inadapting the press to wax carbon work, I mount the inking mechanism on apair of horizontal guides 1 and 8. At each end of these guides aremounted shafts 1' and 8' which carry sprocket wheels 9 and 10 whichcarry a chain II the ends of which are secured to the inking mechanismas clearly seen in Fig. 4 with the'result, as the sprockets areintermittently oscillated in any suitable or convenient manner which isnot shown as such mechanism forms no part of my invention, areclprocatory motion is imparted to said inking mechanism. The operatingmechanism is so timed that the inking mechanism is stationary when it isout from under the platen 5,

so that the reciprocation vertically of the type bed will cause it topress the sheet of paper against the form on-the reciprocating type bed6. The inking mechanism comprises an ink fountain l2 and an ink fountainroller I3. Electric elements 14 are mounted adjacent the ink fountain tomelt the wax carbon compound therein'and maintain it at the requiredtemperature. A ductor roller 16, which intermittently contacts the inkfountain roller I3 carries the carbon to a vibrator roller 11. These.rollers may be positively driven by mounting gears I3, l6 and I1respectively on each shaft so that when the ductor roller 16 contactseither the ink fountain roller N or the vibrator 11, the ductor rollerIE will be positively driven. The vibrator roller 11 is also providedwith an electric heating element l8. A rider composition roller l9contacts the vibrator roller 11 and a distributor roller 20, whichcontacts a composition roller 21.

The roller 2| carries the carbon to a large steel vibrator roller 22which transmits it to a distributor roller 23 which delivers it to theink cylinder 24. This cylinder 24 is preferably provided with aplurality of electric heating elements 25 to maintain the carbon at therequired temperature. Form rollers 26, 21 and 28 receive the'wax carbonfrom the ink cylinder 24 and. deliver it to the form on the type bed 6.As seen in Figs. 4 and 5, a train of gearing I9, 2D, 21', 22 and 23' isprovided to positively drive the rollers l1, I9, 20, 2|, 22 and 23.

The ink cylinder 24 is driven by a chain 29- carried by sprockets 30, 3|and 32. The latter is positively rotated by means (not shown). It willbe obvious from the foregoing that not only the rollers which carry thewax carbon from the ink fountain are positively driven but that the inkcylinder 24 is also positively driven. The ink cylinder 24 which asexplained 'is positively driven by sprocket 30, contacts form inkingrollers 26, 21, and 28, distributing the wax carbon thereon. These forminking rollers 28, 21 and 26 are positively driven by gear 40, sprocket4|, chain 42, sprocket 43, chain 44, sprocket 45, chain 46, sprocket 41,respectively, through the reciprocation of said gear 40 over rack 48.The form inking rollers 26, 21 and 28 are held yieldingly against theink cylinder 24 1 by means of coil springs 26, 21' and 28' which aremounted in the form inking roller carriage ,50 which slides upon theguides 1 and 8. The coil springs 26 21' and 28, as clearly seen inroller 24.

It may be found desirable to locate an electric heating element adjacentrollers 20 and 2i and to mount an element 35 in the large steel vibratorroller 22. It is also necessary to mount a plurality of electric heatingelements 36 in the type bed 6. The'operatio'n of the press, it isbelieved, will be clear from the foregoing description.

It will also be seen that I have provided means to maintain all partsofthe press which contact the wax carbon at the necessary temperature.

Having described my invention what I regard as new and desire to secureby Letters Patent is:

1. In a printing press, a vertical standard, a platen verticallyadjustable thereon, a heated type bed, an inking mechanism comprising anink fountain, an ink fountain roller, a ductor roller, vibrating anddistributing rollers, a rotating ink cylinder, form rollers whichcontact rrid ink cylinder, means to positively drive all of sa drollers, means to reciprocate said form rollers across the said typebed, said means comprising a pair of horizontal guides on which saidform rollers are slidable, a sprocket at each end thereof, a chain onsaid sprockets, said form rollers being secured to said chain wherebyits movement will move said form rollers.
